I/O Logic Board
The I/O logic board includes all the I/O interfaces, video and display support, and expansion bays. The PC Card cardcage mechanism (CardBus slots) is a separate part that connects to the I/O logic board.
The I/O logic board also includes two I/O controller ICs that integrate most of the standard Macintosh I/O controllers such as SCSI, SCC, IDE, floppy disk, sound, Ethernet, and VIA.
